Mountains of Arkansas The Ozark Mountains of Arkansas are the largest mountain range between the Appalachian Mountains in the East and the Rocky Mountains in the West.

The Ozark Mountains of Arkansas may have been named for Aux Arc, a French trading post located there in the 1700s. In French, Aux Arc means "at the bow." The limestone that is found there wears away easily and is responsible for many unusual geographic features, such as caves, sinkholes and underground streams. The Ozarks region is also known for its folk crafts and outdoor recreation.
